Question

I really need help with this. I don't need help solving the entire problem, just in figuring out in what order.

A jet plane starts from rest on a runway. It accelerates uniformly at a rate of 20m/s^2. The equation for computing the distance traveled is d = (1/2)at^2.

a. Find the distance traveled at the end of each second for five seconds.

I know this is a function, but I need to know if I should apply the exponent first or multiply (at) and then distribute the exponent. Seriously, I tried it and know for a fact my answer shouldn't be 1 x 10^31...

Answer 1

I don't believe your equation is correct. I am sure it is: d= Vi + 1/2at^2

Answer 2

Oh, I see your question, one second.

Answer 3

Yeah, that's the equation my teacher told me to use.

Answer 4

d = 0 + 1/2(20)(1)^2 = 10
d = 10 + 1/2(20)(2)^2 = 50
d = 50 + 1/2(20)(3)^2 = 140
d = 140 + 1/2(20)(4)^2 = 300
d = 300 + 1/2(20)(5)^2 = 550
Not sure if that's right, or if it should be 1 second every time.

Answer 5

d = 0 + 1/2(20)(1)^2 = 10 d = 10 + 1/2(20)(1)^2 = 20 d = 20 + 1/2(20)(1)^2 = 30 d = 30 + 1/2(20)(1)^2 = 40 d = 40 + 1/2(20)(1)^2 = 50
